Compact, easy to carry pocket tool performs four separate cleaning functions to help you quickly restore the critical bolt/carrier tolerances that can be compromised by carbon buildup after prolonged shooting. Use as a bolt scraper, firing pin cleaner, patch holder for swabbing the bolt recess, and scraper for removing carbon in the carrier. Plus, the center of the tool is equipped with a ¼" hex head recess to use as a driver. Carry a few ¼" driver bits, and you’re all set to make adjustments that keep your rifle tuned and shooting.
